Abstract: <P>PROBLEM TO BE SOLVED: To provide a hydraulic driving device capable of absorbing the effects of individual differences on the characteristics of supply of hydraulic oil during a blade operation and regulating the supply flow of hydraulic oil into a hydraulic cylinder for blade driving, to prevent an unintended tilt operation from occurring during pitch operation.  <P>SOLUTION: In this hydraulic driving device for a blade, a first control valve for controlling the supply flow of hydraulic oil into a first hydraulic cylinder has a first flow characteristic having the increasing grade of supply flow which is smaller than the increasing grade at a first threshold in a region where a spool stroke amount exceeds the first threshold. A second control valve for controlling the supply flow into a second hydraulic cylinder has a second flow characteristic having the increasing grade which is larger than the increasing grade of the first flow characteristic in a region where the spool stroke amount exceeds a second threshold smaller than the first threshold. The supply flow of hydraulic oil to the second hydraulic cylinder is increased over the supply flow of hydraulic oil into the first hydraulic cylinder due to an increase in the spool stroke amount in the area where the spool stroke amount exceeds the second threshold.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for testing the quality of a long solid insulation cable which enables attainment of a test covering a full length by almost uniform inversion wave and finishing of a direct current short circuit operation at one time.  <P>SOLUTION: A lead cable 6 is connected to one end part 1a of a cable 1 to be tested and a prescribed direct current voltage is impressed from a direct current voltage generating device 2 on the other end part 1c of the lead cable 6. Then, a high voltage portion of the other end part 1c and the grounding are short-circuited by a sphere gap 3 for short circuit so as to perform an operation of cutting the direct current impressed voltage and generating an inversion waveform. The prescribed direct current voltage being imposed continuously for a prescribed time, subsequently, an electric tree generated in the cutting process is subjected to development breakage and the test of the quality of the long solid insulation cable over the full length thereof is performed. Since the portion of the short-circuited end side wherein no effective inversion wave is generated is replaced by the lead cable 6, the effective inversion wave is generated in the cable to be tested, over the full length thereof. Therefore, the direct current short circuit operation is finished at one time.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and an instrument for measuring particles for measuring the diffusion coefficient of nanoparticles and the particle size thereof at a satisfactory S/N and sensitivity, further measuring even a suspension specimen which is made by dispersing a measured particle group in a medium and includes high conductivity with dielectric migration force hardly acting thereon, and performing accurate measurement even if the composition and temperature of the specimen suspension vary.  <P>SOLUTION: By applying an ultrasonic wave to the specimen suspension made by movably dispersing the measured particle group in the medium, the particle group is moved to cause diffraction grating to be generated owing to a density distribution of the particle group in the medium. A parallel light beam is applied to the diffraction grating to measure diffracted light obtained. Information on the diffusion coefficient of the particle group is obtained from a time change in the intensity of the diffracted light after a time point when the application of the ultrasonic wave is stopped. The ultrasonic wave applied to the specimen suspension is caused to be an ultrasonic wave allowing a grating vector component of the diffraction grating by the particle group to be constant irrespective of the composition and temperature of the specimen suspension.  <P>COPYRIGHT: (C)2011,JPO&INPIT
